upgrade from 2.23 to 2.25 seems to remove support for java.time.Instant

[pjfanning]

• Relates to Update influxdb-java to 2.25 apache/pekko-connectors#1024
• I'm just trying to work out whether this is a regression issue - I checked the release notes and couldn't see anything listed that relates to this
• I would appreciate any pointers on how to fix this

Runtime exceptions look like:

[error] Test docs.javadsl.InfluxDbSourceTest.streamRawQueryResult failed: org.influxdb.InfluxDBMapperException: Unsupported type class java.time.Instant for column time, took 0.013 sec
[error]     at org.influxdb.dto.Point$Builder.setField(Point.java:420)
[error]     at org.influxdb.dto.Point$Builder.addFieldByAttribute(Point.java:369)

[error]     at org.influxdb.impl.InfluxDBMapper.save(InfluxDBMapper.java:53)

Our code looks like:

InfluxDBMapper influxDBMapper = new InfluxDBMapper(influxDB);
... create instance to save and that class has a java.time.Instant field
influxDBMapper.save(data);
